COOL INVENTIONS

From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go．This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy．Solar panels on the Eclectic's roof absorb sun rays when you're driving．On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked．The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged．Zipping (迅速行進(jìn)) around the neighborhood has never been better.

Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries．There are two sets of metal electrodes (電極) inside the water tank．Water contains ions (離子) that carry negative and positive charges．These ions complete a charge between the electrodes, creating enough energy to power the clock．Just refill the tank every few weeks, and this clock will keep on ticking.

Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier．(The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine．Then a rocket fires up, pushing the SSC past 1,000 miles an hour．In order to keep the car streamlined (流線型的), the driver lies back at a 45-degree angle.

You're having a blast at your friend's birthday party．But when it's time to bring out the cake, everyone crowds around, blocking your view．No worries．Throw the Triops into the air, and this clever camera captures the view from above．The Triops can take three pictures at once, each from different angles．You can also record sounds and command the Triops to start shooting whenever it hears that noise．That's one smart camera.

Boiler rooms are often dirty and steamy，but this one is clean and cool.Fox Point is a very new 47?unit living building in South Bronx，one of the city’s poorest areas.Two?thirds of the people living there are formerly (以前) homeless people，whose rent is paid by the government.The rest are low?income families.The boiler room has special equipment，which produces energy for electricity and heat.It reuses heat that would otherwise be lost to the air，reducing carbon emissions(碳排放)while also cutting costs.

Fox Point is operated by Palladia，a group that specializes in providing housing and services to needy people.Palladia received support from Enterprise Community Partners (ECP)，which helps build affordable housing by providing support to housing developers.

ECP has created national standards for healthy，environmentally (環(huán)境方面) clever and affordable homes which are called the Green Communities Standards.These standards include water keeping，energy saving and the use of environmentally friendly building materials.Meeting the standards increases housing construction costs by 2%，which is rapidly paid back by lower running costs.Even the positioning of a window to get most daylight can help save energy.

Michael Bloomberg，New York’s mayor，plans to create 165,000 affordable housing units for 500,000 New Yorkers.Almost 80% of New York City’s greenhouse gas emissions come from buildings，and 40% of those are caused by housing.So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD)，whose duty is to develop and keep the city’s supply of affordable housing，will require all its new projects to follow ECP’s green standards.

Similar measures have been taken by other cities，such as Cleveland and Denver，but New York’s DHPD is the largest city developer of affordable housing in the country.(2010·四川，B)

Celebrating sleep

World Sleep Day, observed on 21 March, was created to bring attention to the growing number of sleep problems worldwide. Sleep is a natural part of human life, but many people in the modern world ignore its importance. As a result, sleep problems are increasingly common.

In 2002, scientists at the University of Athens in Greece conducted a survey of over 35,000 people in 10 countries around the world, including China, Belgium and South Africa. Of the people that responded to the survey, 24 percent said that they did not sleep well, and based on their responses, 31.6 percent were diagnosed with insomnia (失眠) and another 17.5 percent were diagnosed with borderline insomnia. In addition, 30.7 percent of survey respondents reported visiting a doctor for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.

Overall, the survey found that many people suffer from the effects of poor quality sleep, some examples of which are being unable to fall asleep and waking up in the middle of the night. The main factors causing these problems are pressure from school or work and a fast pace of life, but noise pollution and light pollution also interfere with sleep and contribute to poor quality sleep. The survey’s findings are particularly troubling because large numbers of people were found to have difficulty sleeping at night. The short­term effects of this are tiredness and trouble concentrating. If this happens for a long time, the risk of gaining weight and having a heart attack may increase.

There are many things you can do to improve the quality of your sleep. First, you should have regular sleep habits. Try to go to bed and wake up around the same time each day. You also need to make your bedroom a cool, dark, quiet place to sleep so that heat, light and noise do not disturb you. At night, you should also avoid things that contain caffeine, such as chocolate, coffee, tea and many soft drinks, as caffeine may keep you from sleeping.

Getting a good night’s sleep is important for everyone. By following the advice above, you can rest better at night and work better during the day.
